commonly used in the manufacture of soap. It has been found that thesoap when used in a granulated condition is eminently suitable for themanufacture of the paste and soap. in that condition is recommended.

The paste is dissolved in a dye bath which has been already prepared andin which preferably the Diamond dyes are used in the proportionapproximately of four tabletherein is then heated-gently and allowed tosimmer for about fifteen minutes. In using the dyes, of course, forwooland silk animal fabric dyes are used and for cotton and linen vegetablefiber dyesare employed and it has been found that thepaste of this in-"vention reacts in a highly satisfactory mannerwitheither type of dye.

By the use of my paste in they dyebath spoonfuls of paste to each poundof material to be dyed. The-bath with the paste above example settingout the ingredients of my paste and the method and procedure to befollowed in combining the ingredients is simply by way of example and isnot to be construed in a limiting sense in any way whatsoever. Theproportions "of the ingredients may be varied within certain limits andat the. same time they may be combined in slightly different ways withinthe scope of the following claims.
